<DT><A HREF="../TkLib/WindowId.htm">Tk_Window</A> <B>tkwin</B> (in)<DD>
Token for window.
<P></DL>
<H3><A NAME="M5">DESCRIPTION</A></H3>
These procedures may be used to map and unmap windows
managed by Tk.  <B>Tk_MapWindow</B> maps the window given
by <I>tkwin</I>, and also creates an X window corresponding
to <I>tkwin</I> if it does not already exist.  See the
<B><A HREF="../TkLib/CrtWindow.htm">Tk_CreateWindow</A></B> manual entry for information on
deferred window creation.
<B>Tk_UnmapWindow</B> unmaps <I>tkwin</I>'s window
from the screen.
<P>
If <I>tkwin</I> is a child window (i.e. <B><A HREF="../TkLib/CrtWindow.htm">Tk_CreateWindow</A></B> was
used to create a child window), then event handlers interested in map
and unmap events are invoked immediately.  If <I>tkwin</I> is not an
internal window, then the event handlers will be invoked later, after
X has seen the request and returned an event for it.
<P>
These procedures should be used in place of the X procedures
<B>XMapWindow</B> and <B>XUnmapWindow</B>, since they update
Tk's local data structure for <I>tkwin</I>.  Applications
using Tk should not invoke <B>XMapWindow</B> and <B>XUnmapWindow</B>
directly.
